摘要
测量距离方向法校射是我海军舰炮火控系统对海校射的主要方法,但在传统校射模型中,偏差测好时刻发射舰位置由发射时刻的发射舰位置推算而得。若直接用发射舰航向航速推算,则由于瞬时航向航速扰动,误差较大;若通过瞬时航向航速累积推算,则随着时间的增加,累积误差也很大。将舰载导航系统引入舰炮校射,利用舰载组合导航系统直接测得发射时刻和偏差测好时刻的发射舰位置,从而建立校射模型。仿真结果表明,该方法对提高舰炮校射精度,缩短系统反应时间,增强舰炮武器系统的作战效能有着重要的现实意义和军事意义。
Firing calibration in measure distance and azimuth method is the main firing calibration method of navy currently. But in the traditional firing calibration model, the final worship-location （when bias is observed） is calculated by the initial Worship-location. This calculation carried out by two methods, one is calculated by initial course and speed directly, the other is cumulated by instantaneous course and instantaneous speed. The first method will cause errors interfered by instantaneous course and instantaneous speed, and along with time elapse, the second method will also result in large errors. This paper establishes a new shipboard gun＇s firing calibration model which based on shipboard navigation system, obtains the initial and final worship-location directly by navigation system. The results of simulation shows that this method is effective in improving naval gun＇s firing precision and shorting system reaction time, has great practical and martial signification.
